To all whmititl may concern:

Beit'knoivn that I. MAn'rrN Leners, a citizen of the German Republ1c,.residing'at BerlinFriedenau, Germany, have invented `Jicertain Improvements in Adding Machines, .forWvhich-.I"'have filed.an application in Geiiiay `on Uctober th, 1919, and ofl whichthe following is a specification.

This invention relates to an adding'maiQ, chine particularly' for adding the numbers represented by dierently disposed perfo-` rations on statistical and like cards, and 'the invention consists essentially in arranging thenumeral wheels of a totalizing counter 5 on la rock shaft whereby they are alternately brought into mesh with Setting seci tors and with sectors eilecting the transfer of the tens, the settingl sectors being themselves st Vthrough the medium of the cards 19 and 'theiry setting movement communicated to the totalizinp; counter while they are re turni'rtcr Ato their. initial position, Means are also provided whereby the items are print siretl, by the same type-wheels and with the exclusion of cani` Figures@ Fig. '1 ofthe accompanying drawings repj.-

On a shaft 2 which is held in twovertical plates 1, a plurality of setting sectors 3 is rotatably arranged; one sector being` provided for each plate in the numbers to be dealt with. The sectors are independent of each other. and each sector is lactuated by a spring; 4 which tends to turn it on the ed `continuously and the totals whenever de` ciphers in front ot the signifi-` shaft. The movement is normally opposed by'a universal bar 5 which rocks by means of arms 6 'about the shaft 2. The bar 54 is controlled by a cam 7 which is inounted on a shaft 38, one of the arms 6 being pro- `vided with a roller 8 (Figs. 2, 3 and 7) whereby it bears against the cam. Each sector m hes with a pinion 9 which is formed with 11 teeth and `which isicoinacted to a ratchet wheel 10 and to a type Wheel 11. The ratchet Wheel is provided with 1'1 teeth ten of which are represented by types on the wheel 11, the latter having one blank space. The types carry the figures 1 to 9 and O. Each ratchet wheel cooperates with a detent lever 33 which turns loosely about a shaft 32 and which is inliuenced by .a springr 35 tending to turn it. into engage ment with the wheel or arresting its moveY ment. Normally the evers 33 are held-.ont ofrengagenient with the ratchet wheels by s ringl catches 34 connected to a support 47.

perated detent levers are restoredto' the normal position b v a universal bar 36 which for that purpose is operated by a tappct 83 (Fig. 3) formed on a disc connected to the cani shaft v'33. 'A ,leven arm 80, which is "supported 'oir the'gdige of the tappet by means of a rtillerl, is secured to the shaft 32 which carries the bar 36, by means of rigidarrns 37.

The items set up by means of the sectors on the type wheels 11 are printed from these onto a paper strip P which is taken past a platen 57by means of two friction rollers 90 and 91. an ink ribbon F being interposed between the paper and the type Wheels. The friction Vrollers are mounted, together with `the platen 57 in a frame 53 which' rocks about a shaft 54. A lever 58 (Fig. 4) secured to theshaft 54. carries at its free end a roller 6() whereby it is supported on the edge of'a ca'm 61 on theshaft 38. A'

feeding Athe paper strip, the feed roller 91 being connected to a ratchet wheel 55 which isl engaged and turned by a hooked Tbar 56. The latter is pivoted toV aV bell-crank 52 mounted on a shaft 21 which is rocked by a cam 49 secured to the cam shaft 38. A rod 51, which is guidedby the cam shaft, communicates the movement from the cam to the lever 52 by means of a roller :50.

There is e totalizing countercom d of numeral wheels 17 which are loose y arranged on e shaft 13, each .wheel being connected to a pinion 16 having ten teeth. The shaft 13 is held by arms '14 on a rock shaft15 which is actuated by either of two,

cams 39 and 40 (Figs. 2-and 4)., .An 'arm 42 connected to the shaft locariie's et its free end two coaxial rollers .'41 arranged at opposite sides (Fig, 6) for engagement -with grooves, one in the cam 39 and the other in the cam 40. The cams are feathered on the shaft 3S and controlled b asetting lever 44 the free end of whic carries a roller which is disposed between the two cams. The lever 44 is operated by hand for putting the lever 42 into-engagement with either cam.

The transfer of the tens is eected by means of sectors 18* arranged loosely on theY shaft 21. The inions 16 are normali held in contact with these sectors whic and 41hv brush is connected by a wire-75 to en electromagnet 76 whose armature 77 operates, by means of a lever and a connecting link 78, one of the springI catches 34 which retain the detent levers 33. The magnets. are energizecl by a battery 79 which is connected by a wire 80' to e brush contact 81' which slides on the roller 702 The latter is geared to the cam shaft 38's() as to` Vrform the same number of revolutions. an the diameter of the roller is chosen so that one revolution takes the card right through the machine.

Fig. 10 showsja. card by way of example. The portion enclosed between the dotted lines is the one to be dealt with by the adding machine and it contains as many yplaces as there are setting sectors and nuhold the numeral wheels in operated p0si` tion 'with the total ap aring in a window 43. The shaft 15 is roc ed for bringing the pinions into mesh with the sectors 3 for receiving the items from the lutter. The sectors 18IL are integral withilever arms 18*l and 18, the hitter of which are 'actuated by springs 22 tending to turn the sectors` the movement being normally prevented by the abutment of the arm 18," a inst a. universal bar 19 which is connecte by arms 20 to the shaft 21 so as to be rocked by the latter. The movement; of the sectors is also prevented by double-armed levers 24, each sector being formed with a nose-pece 18l which bears normally against a shoulder 29 on one of said levers. Sprin 25.hold the levers 24 in Contact with vt e nose-pieces meral wheels in the machine., The black circles indicate rforatons, each one being made opposite t e'tigureit represents and in the place to which it present instance the perforations represent the number 965031. There is also, at the foot of the card, which enters first into the machine, aline marked 00. In this line perforations are made in all the places tc fifi-left of the 'first significant figure," The card in Fig. 10, for instance, has two perfo .rations in the line 00, since the Vmachine con ,tainsV eight places and since the number 18 which are released by studs 26 connected to the numeral wheels so as tn turn the levers 24 when t wheels, enter the zero osition. iVhen a' lever 24 is thus turned y its allottedstud 26, it is retained in operated position by a spring catch 30 which snaps behind a tooth 27 formed on the lever. The levers are released by the spring catches by means of a universal bar 31 which is held by arms 84 sothat it can frock loosely about t e shaft 15 for depressing the fcatches..

One of the arms 84 isntegragl with a lever arm 62 (Fig. 4) which i's'controlled by n cum 63 mounted on the shaft 38.V l

The sectors 3 may .beset electrically by moans of the device illustrated in Figs. 8 and 9, the perforated cards 72 being taken bv a feed roller and marginal clamping vdiscs 71 past a 'series of contact brushes 74 which 'make contact with the roller 70' through the gerforetions ofthe card. The brushes are' t ted in a holder 73 and each punched4 on the card only contains six laces'.

Fig. 3 shows the cum Tin the norma position. `'I-heportion aof the cum is con; centric' with the shaft. and whiie the cum moves through this distance the lin:` il() of the-card passes under the contact brushes, The. rforutions of this line canse tho respective catches 34 to he wtlnlrawnund their detent levers 33 to he'applied to the ratchet wheels l0 so as to prevent them und their sectors 3 fro moving from iheir initial,.position. fiile thc remaining q-'ni'il lines pass the thro-ugh c and d. passes under the roller R and causes th har' 5 to descend and the nnlocked sectors to turn through ten rogspaces, one cog for each lineg'f Euch linc in which a perforation occurs choses a detcn't 33 corresponding to the place which the poi;- foration occupies. to he applied to the res ective ratchet. .wheel l'so ns lofstop furt er mo ment ofthe sector and of the type wheel. Thus the number representedv on the` card will be set up by the` type. wheels in front of the, platen 57., the appearance of zeros in front of the rst'signicant ii'gifie being prevented ,by the perforations-'made in the line O0. While the curve a-f, which is concentric withthe shaft, passes under the roller 8,"the' platen is applied to the type wheels for printing the item. At the same time lthe shaft 15 is operated so as 1o bring the inions 16 into gear with the sectors 3. en the cemcurve f-g7 comes into play and'turns the bar back through belongs. lThus. in the l0 /llths of its stroke so that thetype wheels lOlwill be zeroized. As the return move ment of the sectors will in each case be equal lo the forward movement. `the numeral Wheels 17 will be set to the number represented on the card. The cani curve lr/-k is also concentric with the shaft. and while it asses under the roller 8, the pinions 16 will e restored to their contact with the sectors 18', and the number printed on the strip P `will appear in the window 43, The icam curve lirestores the 'sectors 3 and thrl type wheels to their initial position whereupon, while the concentric curve i-a passes under-the roller 8, the bar 36 is operated for reengaging the detents 33 to thespringr catches 34. e

Each succeeding card passed through the machine repeats the operation. .The item of each card will be printed separately on the strip Pand added to the total shown by the numeral wheels 17. Any numeral wheel ,reaching the zero position causes, bymeans of its stud 26. the lever 24 of the next higlr er denomination to be turned out of engage nient with the nose-piece 18d and to be ar rested by the catch 30 clear ofttlie path of the nose-.piece and of the respective sectors 18. Afterithea pinions 16 have been brought back into niesh with the sectors V18% the hui' 19 isr lowered, and the sectors previously freedhy meansof the studs 2G will he turned by the `springrs 22 `through one tooth space. .thereby effectii'ig Ithe transfer. .-\n \j numeral wheel reaching the aeroA position during 'such transfer will cause `the Arelease also of the Wheel of the denomination next higher to it so as to pass on the transfer to the latter. 'While the pinions 1G are in mesh we oupled to the lever 4 4 so as to be shiftedy simultaneously 'with the same for putting with the seetois 3. `the sectors lll are rcstored to the `initial position by the cuni 4f) and the bar 19, the catches 30 lieiugpat the same time operated bythe cam G3 und the bar 3l so as to release the levers 2l and cause the Sectors 18" to lie re-arrested thereby.

The total appearing on the totallizing coun-` ter can be lprinted on the strip P'hy means of the type Wheels'. 'll whenever desired. For this purpose the lever il is reversed so asto place the lever 42. whereby the rock shaft l5 is operated. under the control ot the cam 40 whereupon the shaftllS is turned without the insertion of any card. pinions 16 are. after Athe Vsectors 3 have moved through one tooth space and turned the type wheels to the zero position.Y put into gear withy the sectors 3 so as to be rotated j thereby in the reverse direction. Eaclrnumerel wheel 17 is formed with a circurni'ei-` ential lug which normally passes through a gateway formed for the saine in a bar 71. The latter is axially displaceahle and is the `gateways out of register with the lugs.

The

The bnr will 'thus forni a stop for the Wheels and cause them to be arrested in the zero position when turned backwards b v means The lutter and the type wheels will also he arrested. and as the for-4 wurd moi-ement of the type wheels is exactly equal lto the rearward inrvwement of the respectiveinuin'rul wheels. the same number will he presented for printingr us previously appeared on the totalizing counter.

The numeral ,wheels may eithenbe re turned to the initial position before the return .of the sectors 5i. in which case the tot-alizing;r counter will reina-in zeroized, or left in contact 4with their sectors until the type wheels `have been zeroizeth in which case the printed total will he carried` forward for further addition.-

. In order to avoid the printing of ciphers in froiit of the'signiicant. figures of the total. the following arrangement is prof vided: f

'A plurality of pivoted arms 46. one for each sector 3. is arranged so as to .he movable in ahorizontal plane. of each lever has a portion 95 (Fig. 5) adapted to be placed in front of the sector 3 so as to prevent the latter from leavingr its position of rest. Another portion 97 of the end of the arm is hy the 'samefmorement adapted to enter fa notch (Figi) formed on the 'respective numeral wheel 17 so as to prevent :the lutter from movingjrom the zero position, Thearms uresprinQ-actuated' and tend -to move into engagementfwith the sectors and with the numeral Wheels; but are nornmlljv prevented fronifso doing a stop 'el-S (Finn-5) against which thelirst arm rests. the olhernrms heingsnpported" on euch othermbyv means .o'l projections 9G. The stop lf3-'is connectodto the le`ver 44. so aS to be shilted togethorwilh the latter for releasing't-hearms 4G. when the total is to be and .no ciphers ywill he printed in these It is evident that the springf catches 34 may he operated by mechanical instead of electrical means and that the various devices may be applicable to other than cardcontrolled machines.
